Background For Teachers:
Certain conditions must exist for clouds to form - water vapor in the air, temperature change, and particles in the air for the water vapor to condense on. As warm, moist air rises, it begins to cool and condense on dust particles forming water droplets. These water droplets form clouds. They will not fall to Earth because they are too small.
Clouds take different shapes depending on the amount of water vapor available and the speed and direction of the moving air. Clouds are classified according to how they are formed. Below are the main types and their descriptions.
There are cloud charts that you can buy to show what these clouds look like. However, most cloud charts will have more than these basic clouds. They use the prefixes “alto” and “nimbo” to tell more about these three basic clouds. If the prefix “alto” is used, it means middle, referring to the position of the clouds in their respective areas. If the prefix “nimbo” is used, it means water and these clouds will often bring rain.
Intended Learning Outcomes:
Pre-Assessment/Invitation to Learn
Pass to the students the prescribed sheet of blue paper. Ask the students to draw a cloud they have seen in the sky. Have several students show pictures of their clouds to the class. Have some draw their clouds on the board. Discuss how their drawings are alike and different. Tell students they may have all drawn different looking clouds because clouds come in all different shapes and sizes. Tell them there are three main categories that scientists use to classify clouds. With the use of a cloud chart, discuss the three cloud types and see if students can identify the clouds they drew.
Activity 1 - Looking at Clouds
Activity 2 - Constructing Clouds
Review with the students what they learned about clouds. Have them look at pictures from magazines, the library, an Internet site (www.askjeeves.com), or pictures you have taken with a digital camera of the three types of clouds. There are many poetry books that have been written about weather that include poems about clouds. Read a cloud poem to them as they are looking at the pictures.
